Setup for Measuring Light Intensity
You can use the Basic Optics Bench, Basic Optics Light Source,
Polarization Analyzer, Rotary Motion Sensor, Aperture Bracket,
and a Light Sensor to measure the light intensity through the
Polarizers as one Polarizer is rotated relative to the other.
Prepare the Polarizer
Put the second Polarizer in the empty Polarizer Mount that comes
with the Polarization Analyzer.
Mount the Light Source
Put the Basic Optics Light Source at one end of the Basic Optics
Bench. Refer to the OS-8515 instructions. Turn the Light Source
so it produces a “point source” of light that is aimed toward the
other end of the bench.
Mount the Polarization Analyzer
Snap the Polarizer Mount onto the Optics Bench. Snap the Polar-
ization Analyzer with Rotary Motion
Sensor onto the Optics Bench.
Mount the Light Sensor
Snap the Aperture Bracket Holder
with the Light Sensor onto the Optics
Bench with the Light Sensor opening
toward the Light Source
